Binary inputs
I1....I8
– in negative logic:
Each of binary inputs I1....I8 may operate as a counter input or analogue input with
frequency conversion to analogue value. The change of input operating mode is done
during configuration.
Typical connection for counting input is identical to standard input connection for both
negative and positive logic. The only difference lays in counting of pulses appearing on the
input and storing the result in a 32 bit register assigned to this input.
Binary input operating in analogue mode has slightly different connection. It is assumed
that the signal is a square wave with variable frequency in range 0....2kHz, where
momentary frequency corresponds to measured analogue value. The wave usually comes
from a converter exchanging measured analogue value to proportional frequency in defined
range.
5.2. Binary inputs/outputs Q1....Q8
Integral outputs
Q1....Q8
may operate, depending on selected mode as inputs or outputs,
In both cases only positive logic applies.
